apalis/colibri t30: fix record/playback for sgtl5000 codec
Backported commit f997df18c0e4c988de49e984329cefdf6e13ed86
According to the manual [1], SYS_MCLK should base on SYS_FS, not on sample rate.
Calculating SYS_MCLK using sample rate only prevents playing/recording
samples with rate < 16 kHz:
---------------------------------------------------------------
root@apalis-t30:~# aplay test-8k-sample.wav
Playing WAVE 'test-8k-sample.wav' : Signed 16 bit
[...] tegra-snd-apalis-tk1-sgtl5000 tegra-snd-apalis-tk1-sgtl5000.0: ASoC: machine hw_params failed: -22
Little Endian, Rate 8000 Hz, Stereo
aplay: set_params:1403: Unable to install hw params:
...
---------------------------------------------------------------
Using the helper from sgtl5000.h fixes this issue.
To keep determination of sys_fs solid, use a helper in device driver.
